Description
The background of invention
The present invention relates to the most handy a kind of heating furnace apparatus and method of manufacturing such as foam glass or ceramic material continuously.
Foam glass and ceramic material be all with square, fragment of brick and have the form that comprises triangle, circle and avette various shape of cross sections and use.Because the low-density of this material, abrasion, insulating characteristics and quite high intensity thereof well are so can be used as various products.Usually produce foamed material by the mixture that in a pressing mold, mixes a kind of glass or ceramic powder and a kind of suitable blowing agent; Heat this mixture, at first make its sintering, melt then and foam, whereby this mixture expansion and produce hole or bubble therein.
Usually, the mixture of glass or ceramic powder and blowing agent is heated to about 1250 °F, and this material will be sintered or condense.Then this material is heated to 1700 or higher temperature to form the foam block of mecystasis from 1274 °F.Make this expanded material be cooled to about 1050 °F then and make surface cure, must take out foamed material this moment from pressing mold.If do not take out, and if foamed material is further cooled off, then the thermal contraction of pressing mold surpasses the thermal contraction of foamed material, and then this pressing mold is with " pinnings " this foamed material, and is all the more so when especially dismantling temperature as if the pressing mold that makes foamed material be cooled to 100～150.This may cause cooled foamed material crushing or break, and makes pressing mold if not can not dismounting also may be very difficult to dismounting.Background technology
